PRINTING-hIACI-IINE.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed November 12, 1910. Serial No. 591,944.

To all whom, it may concern Be it known that I, GEORGE W. Honninos- \VORTH, citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful PrintingJfachine, of which the following is a specification.

My invention relates to a hand operated printing machine, and more particularly to a machine in which rubber type are used.

The object of my invention is to provide a device which is comparatively inexpensive to manufacture, simple in construction and arrangement and easy to operate, so that the printing may be done by any one who can read.

Another object of my invention is to provide simple and etlicient means for accom plishing the alinement of the face of the type.

.Another object of my invention is to provide ready means for substituting one type form for another.

Another object of the invention is to provide means for equalizing the pressure upon the face of the type to insure evenness in printing.

Another object of my invention is to pro vide means whereby the copy to be printed is displayed upon the back of the type at all times. and in full view of the operator, thus enabling quick changes and substitutionsof the matter to be printed and without dangel of making mistakes.

My invention-is particularly adapted to printing menu cards, or other printed mats ter requiringfew changes, and with these and other objects in view, my invention consists in a type printing machine comprising a base, a printing platen, an open form suspended above said platen, type arranged in said form, an inking pad placed at one side of said platen and a slide rod adapted to carry the form and type back and forth from the inking pad to the platen.

My invention also consists in the details of construction and arrangement and in the parts and combination of parts as herein set forth and claimed.

In the accompanying drawing which serves to illustrate the construction and use of my invention: Figure 1 is a top or plan view of the device showing, at the right, the printing form in position for printing, and, at. the left, an inking pad. Fig. 2 is a vertical section on the line AB of Fig. 1. Fig.

3 is an end elevation. Fig. fl is an enlarged detail end elevation of the frames and means for detachably connecting and holding them together. Fig. 5 is a side elevation of a spacing blank shown full size. Fig. 6 is a top view of the same. Fig. 7 is a top view of a metal bridge, and Fig. 8 is a side eleva tion of same mounted in position upon the side rods of the printing form, which rods are shown in section. Fig. 9 is a perspectIVO view of a rectangular block of wood having upon its lower edge rubber type, and upon its upper edge a print thereof. Fig. 10 is a perspective view of a filling block.

In the embodiment of my invention, as

illustrated and which shows a preferred construction, I provide a base 1, upon which I mount a rod 2, held in place by supports 3, 3 and 3". rod 2 is an outer carrying frame 4, it being attached to the rod by bearings 5 and 5. The frame is provided with a suitable handle 6. Placed within frame at is a type holding form 7, consisting of cross-bars 8 and S at each end, connected together at the sides by rods 9. Pivots 10 and 10' are Slidably mounted upon the secured to thecross-bars 8 and '8 respectively, and are detachably held in open bearings 11 on the lower sides of the carrying frame t by means of springs 12 and 12. These springs are preferably constructed as clearly shown in Figsyl, 3 and 4:, in which they are shown as U-shaped and pivoted at one end 13 to the carrying-frame 4t, and the other end of said springs are curved and clamp beneath said pivots 10 and 10' to hold said type form? 1n fixed longitudinal relation to the carrying frame l, but allowing it to turn on said pivots 10 and.

10. \Vhile it is not absolutely necessary for the form 7 to turn freely upon the pivots 10 and 10 to make a printed' impression yet if it does not turn upon said pivots it will be seen that the outer edge of the printing form 7, being farthe r from the fulcrums or rod 2 than the other portions of the printing form will move faster than the inner edge thereof and in consequence the type will print heavier on one portion of the form than on the other; also if a number of sheets of paper are placed on the platen at one time the swinging form 7 will adjust itself automatically.

The type holding form 7 is provided with a series of spacing blanks 14,-having extending lugs 15 at their ends to support them in position upon the side rods 9. These spacing blanks are provided toseparate the lines of type and also serve to hold them in place. They are also provided with bridges 16 (as shownin Figs. 7 and 8) having recessed ends adapted to engage the rods 9 and to be held in fixed vertical relation to said rods, and slidable longitudinally thereon. These bridges are-preferably formed of metal and are provided to hold the type rigidly in place when all are clamped together, and also to prevent the type from springing upward while under pressure when inking or printing. Transverse extensions 17 are preferably provided on one end of the bridges 16 to engage the upper and lower surfaces of the rod 9 to hold the bridge and type 1n vertical position while the type form is.

being set up. I

As shown in Fig. 9, a section of rubber type 18 is preferably mounted upon the lower edge of a rectangular block of wood 19, which has upon its upper edge a print or label 20 of said type. A thumb screw 21 is mounted in and extends through the type I holding frame bar 8 and pivot 10' for the purpose of clamping the type, spacing blanks and bridges together. type alining surface 22 is mounted upon the base 1 beneath the type holding form7, and is provided upon its outer, upper surface with supports 23 adapted to engage type spacethe rows of type sufficiently apart and holdthem in position. Ordinarily a bridge is required every four or five .lines and a spacing blank is generally used between each row of type. The space between the linesfis regulated by the thickness of the spacing blank and'one or more spacing blanks as desired, may be used between the lines. Where the lines of type are not complete, the intervening spaces are provided with filling blocks 24: as shown in Fig.710, and these filling blocks are provided with knobs 25 by which they are handled, and are provided with shoulders 25extending laterally for the purpose of engaging the spacing blanks or type blocks and holdin the filling blocks above the platen.

In the use of myinvention I preferably provide a resilientpad 26 formed of felt or other suitable material, which is placed upon A platen or the platen or'type alining surface 22 after the type have been set and clamped in place. This insures a complete engagement of the entire face of each type with the paper, and results in a clear, distinct impression of all of the type. By inserting the resilient pad,

the pressure exerted in printing is brought to bear upon the paper and resilient pad instead of upon pins 23 which support the type holding form 7. The longitudinal rigidity ,of parts being. essential, it is necessary to have the fulcrums of the carrying frame in fixed relation with the base. I therefore provide the central support 3' for the rod 2, so that when the printing form is in positionfor printing or for inking, one of the bearings of the carrying frame a will be'in contactwith one of the outer supports, and the other bearing will be in contact with the central support, thus insuring the rod; 2 against being sprung upward When-there, is. downward pressure upon the handled in printing "or inking. A supply and type drawer 27 is preferably provided in the base of the machine. 1 a

The operation of my device-is as follows 2 Slide the carrying frame 4: as far to the right as possible, as shown in Fig. 1,, the

type holding form7 being mounted within the carrying frames and resting upon the supports 23 as shown in Fig. 2.' Place the llnes of type face downward upon the platen or type aim ng surface, displaying same in such position as will produce the most desired effects, using spacing blanksv 14 and bridges .16, between said lines of type to properly. spaceand hold the type. The filling blocks. 2 L are inserted in the spaces not. voccupied by the type. a The spacing blanks, bridges, type and filling blocks are then clamped together securelyby means of a thumb-screw 21. Theframe is then raised for the purpose of placing a resilient pad 26 .upo'n thefplatento insure a perfect contact between the paper placed thereon to be printed and the face of the type. The printing, is then accomplished by simply sliding the form to the left over the inking pad 28 and pressing downwardly to. inkthe. type by engagement therewith, then sliding the printing form to theright in position over the platen and pressing the form clownwardly upon a sheet of paper to be printed, and repeating the operation. When it is desired to substitute one printing form for ,another within the machine, the type holding form 7 is removed from the carrying frame 4 by simply raising the springs 12 upwardly upon their'pivots 13 until their free curved ends are disengaged from the.

pivots l0 and 10.

This will permit the carrying. frame to be raisedby the handle out of engagement with the type form, which will then rest upon the'pins 23, and

another type form can then, be substituted, by merely reversing the operatlon ust described.

It will be seen that this machine is one,

in the items to be printed are necessary. It

requires but a few minutes to make such changes without settlng separate letters or even words, the lines of rubber type being made to suit the requirements of the individual user. An especially desirable feature is that each line or portion of a line of type is labeled on the upper edge so that the entire card or other matter to be printed is in plain print precisely where it is to be printed, and this enables the user to rearrange the items and substitute others without reference to the face of the type or printing a copy or without removing it from the device. The user is less liable to make mistakes in this way than otherwise. In addition to being simple and easy of opera tion, the type automatically line up to a true printing surface, thus giving an even, clear impression unobtainable in other rubber type machines, owing to the fact that it is impossible to make rubber type of equal thickness.

Many modifications of my invention may be made without departing from its spirit and scope, as for instance, if desired metal type may be employed instead of rubber type, and for this reason I do not wish to be confined to the particular construction and arrangement of parts set forth or to the materials used in their construction.
